When Amy Adams accepted the Golden Globe Award for her performance in “American Hustle” Sunday night, she made sure to thank Megan Ellison from the stage.

So did Spike Jonze, the writer-director of “Her,” who won the award for best screenplay. Ellison, the 27-year-old daughter of Oracle Corp. billionaire Larry Ellison, invested in the films through her Los Angeles-based Annapurna Pictures and is credited as a producer of both.

The wins (and Thursday’s 17 Oscar nominations) punctuate Ellison’s ascent in Hollywood. Backed by her father’s fortune, she received her first producing credit in 2010, according to the Internet Movie Database, a research website. Since then she’s produced films including “Zero Dark Thirty” and “True Grit,” both of which were nominated for Academy Awards.

“They’re trying to build a company,” said Robert Marich, author of “Marketing to Moviegoers.” The diversity of the choices shows ‘there’s not a particular theme or message.’”

Annapurna was founded to make “sophisticated, high-quality films that might otherwise be deemed risky by contemporary Hollywood studios,” according to its website.

Ellison is following in the footsteps of other rich Americans who have tried their hands in filmmaking, from Howard Hughes and Joe Kennedy to Mark Cuban.

“There’s something very glamorous obviously about Hollywood,” said Richard Walter, a film professor at the University of California at Los Angeles. “They’re slumming.”

Annapurna’s biggest box-office hit is the 2010 release “True Grit,” a remake of the John Wayne movie featuring Jeff Bridges in the title role of Rooster Cogburn.

The picture, written and directed by brothers Joel and Ethan Coen, cost $38 million to make had worldwide ticket sales of $252 million, according to Box Office Mojo, another research website. Studios and their partners typically split the revenue with theaters, with the studio also bearing marketing expenses.

“American Hustle,” about a 1970s-era FBI sting, had a $40 million budget and has taken in $101 million so far, while “Her,” featuring Joaquin Phoenix as a man who falls in love with the sultry voice of a computer operating system, was expanded to more theaters last weekend and has $8.8 million in total revenue, according to Box Office Mojo.

Ellison declined to comment, according to an e-mail from her spokeswoman, Bebe Lerner.

Next up for Ellison — a reboot of the “Terminator” movie series with her brother, David Ellison, whose Skydance Productions has emerged as a production and co-financing partner with Viacom Inc.’s Paramount Pictures. They are opening “Jack Ryan: Shadow Recruit” today.

Both siblings attended film school at the University of Southern California, according to a March 2013 article in Vanity Fair, which reported Megan Ellison has received at least $200 million from her father and as much as $2 billion.

Neither number is correct, according to Lerner, who declined to elaborate.
